Abarelix is a synthetic peptide hormone used to treat advanced prostate cancer. It works by blocking the effects of gonadotropin-releasing hormone (GnRH), which decreases levels of testosterone in the body. Abarelix is usually given as an injection under the skin once a month. Common side effects of this medication include hot flashes, headaches, nausea, fatigue, and muscle pain.
Abarelix, sold under the brand name Plenaxis, is an injectable medication that is classified as a gonadotropin-releasing hormone (GnRH) antagonist. It is primarily used to treat advanced prostate cancer in some countries.
Its mechanism of action involves blocking the GnRH receptors in the pituitary gland, thereby suppressing the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones normally stimulate the testes to produce testosterone, and by decreasing their levels, abarelix effectively reduces testosterone production in males with prostate cancer.
